Best Air Line Couplers

[wharvey]

Hey guys,

I'm sick of my quick couplers developing air leaks after little use. I've bought the from Northern Tool, Harbor Freight, Lowe's etc but they all eventually ****. Any advice on the best, most dependable couplers I can get out there? My compressor is this one:

I haven't run a permanent pipe yet and I use 3/8 inch line.

Thanks!!

I( converted my whole shop over to Milton V style fittings (high flow). Work great, don't leak. Got them here http://www.floydtool.com/air_hose_fittings.htm

 

[bluebolt]

I only use genuine Milton connectors, they work great!

 

[shampoop]

+1 on the milton v series. Just look at the size of the hole vs everything else.

'nother vote for Milton, I use T type.

You then need to decide what series you are going to use.

Here are the styles available.

They also make a universal coupler.

You might take a look at that so you can use your old fittings.

Over all Milton connectors are the best do to quality and availability. Be for you decide I suggest you travel to most hardware and auto parts stores in you area and buy what they all have in common. Eventually some will discontinue that line. Consider using 3/8 connectors if the high flows aren't available in good supply.

Legris C9000 safety couplers are my favorite, but they only come in plastic external bodies. I thought my brother found stainless ones but I cant find them. They connect with standard industrial style air fittings.

Prevost makes an awesome coupler as well, they outlast the brass ones 4-1 and most of the steel ones by at least 2-1 with the way they are designed. Not cheap, but well worth the cash in my opinion.

Yep, same here. They are all that I use.

for Milton V fittings

Converted all mine over to them last year. Very noticeable difference.

 

[djmartins]

Milton V, get them at Carquest or Northern Tool......

 

[wharvey]

Awesome -- thanks for all the help guys. I'll go check out the Milton V's!

 

[RECox286]

I'm sure that there are other than Milton couplers available, however, for what it's

worth, Milton is available where ever you go. The others (?) , I guess you have to

really hunt for them. I have been a Milton kind of guy for 35 years, and yes, I have

worn them out. The shell of the coupler remains intact, but the replacable "faucet

washer" does suffer over many years of use. The good thing is the washer is reversable.

I bet you would wear out too, given as much use as my couplers get.

Milton "V" again & again!

 

[RacerX]

Another vote here for the Milton "V" connectors. I've been swapping over to them from my previous Milton "A" style and various no name A style that leak like crazy. The no name ones tolerances are way off on the machining.

Nice thing about the "V" is the "A" will also connect to it if you have a tool you haven't changed the connector on yet. It leaks, but can still get the job done.

The "M" syle Milton also work with the "V" couplers but leak also some times.

 

[AndyA]

I use milton m-style.

I also have a few of the prevost pushbutton connectors, m-style. Those are great for use with gloves. Just push the connection together until it clicks, no fiddling with pulling back the ring. The pushbutton release is large enough to operate with gloves also.

 

[fflintstone]

I vote for the Milton H couplers, they are the high flow type (3/8 body) as well.

I am not familure with the V couplers everyone mentioned. Campbell Hausfield sells the 3/8 body I/M which is the same as the Milton H series. I have been running these plugs for 15 years now and love them.

 

[thewal]

I am curious about something, I use the P styles couplers S1809 from Milton rated at 68 SCFM but I heard that the V style has 74 SCFM and are easier to connect than the p style. I also noticed that the p style has a larger hole than the V style s760. My question is what is better in terms of performance at the tool. How is the V style have more SCFM yet it is smaller in diameter.
Can someone assist with this question. I want to utilize the power of my air tools as they are all 1/4 inch NPTM.

Thanks!

id assume that the discharge outlet of the fitting is not the most restricted point of the coupler. the female coupler probably is where the restriction is.

 

[Speed-Racer]

I like the Milton A style. You can push the fitting on the coupler without pulling back the sleeve. Do a search, this topic comes up occasionally.

 

[ILDurable]

As everyone else has been saying, Milton would be great to go to. But also check out Amflo! High quality and they have a nice, high flow to them.

 

[thewal]

I agree that milton is the way to go but i am just debating to stick with P style or V style couplers.

 

[ElectroLight]

Another Milton M-style guy here, can't go wrong with Milton products.

 

[devoncoolman]

I use the Milton M style. and only genuine Milton products only way to go. I drop them throw them and abuse the **** out of them and they still out last the Chinese one 20 to 1 and don't leak. It really doesn't matter what style u pick just pick whats available. The "M" and "A" styles have been most popular in the auto industry for years. the Lincolns are finaly starting the disappear. Always hatted those. lol

 

[T_Raven]

I can't find the answer I'm looking for online. How is V different from M?

 

[thewal]

I can't find info as well between the difference 0f V and P

 

[TwoInch]

v style couplings are high flow. they have a larger inside diameter. iirc, they were designed for HPLV sprayers...

 

[TwoInch]

the nice thing is that the V style female will accept the M and A style male also.

 

[thewal]

are they better then the P style? P style diameter is slightly bigger. but in terms of scfm the V is rated at 74 compare to the p at 68, not sure how since the diameter on the p is bigger.

 

[TwoInch]

im assuming the actual restriction point is in the female coupling and not the actual diameter inside the male "port" the P style is a 3/8ths coupling, and the V series are standard 1/4" couplings. the Ps are much larger in overall size, and will add much bulk to the end of your airline and tool.

either way, 68scfm and 74scfm are close enough to not matter at all for anything garage related.

 

[RCStocker]

Milton. It is a no brainer!

 

[blacK20]

Like already mentioned the nice thing about V couplers is that they'll accept M and A fittings as well for tools that you don't want as much power on. I use V fittings my impacts and A fittings on my ratchets and drill etc.

 

[wise]

I've extensively used M's P's L's and V's and I'd have to say V's fail the least, but they will all eventually fail.

 

[RCL]

Had a cheap offshore coupler on my compressor that was really irritating me.
Just installed a new Milton and problem solved.

 

[thewal]

The one thing that i hate about the p style is that they are a pain to connect and disconnect plus they are bulkier.

there really isnt a reason to go with 3/8" size couplers for normal garage type air tools.

i dont think i have ever heard of someone wanting less power in an air tool... especially ratchets and drills. generally you want them to be running at full potential.
